To all whom it may concern:

Be it known that I, JOHN P. EUsTIs, a citizen of the United States ofAmerica, residing at Newton,'Middlesex county, Massachusetts, haveinvented certain new and useful Improvements in Methods of Making Jointsfor Wires or Rods, of which the following is a specification.

This invention relates to methods of making joints for wires or rods,and has for its object the production of a relatively broad jointbetween two right-angularly connected wires or rods, as insponge-holders, soapholders and other wire goods.

This application is a division of applicants prior application, Ser. No.483,234, filed March 18, 1909.

The particular object of the invention is to provide an improved methodfor the production of a ball-like effect at such joints, in which theball is relatively wide as compared with the width of the wire or rodsused. This is not new of itself, but the manner in which the effect isproduced is simpler and more efficient than any other of which I amaware. There are a number of methods open to use at the present time formaking joints for wires as followsz A rod is drilled transversely andthe end of a wire of less diameter is set in the hole. Or, a turned ballhaving one hole drilled clear through and another hole drilled half Waythrough at right angles to the other hole is used and the wires to bejoined are set in these holes. Or, an eyelet is soldered to the end of awire and the flange formed up to fit the circumference of the rod atright angles to it. Or, the end of a wire or rod is forged or rolled toreduce said end and to broaden it relatively to the wire, so as toproduce a cross section in which there are fiat edge-portions and anintermediate con vex portion of the same width as the original wire orrod.

The method formin the subject of this invention is wholly di erenttherefrom and these differences will be made apparent by the drawings,specification and claim. The steps of the method are illustrated in theacccompanying drawings in which- Figure 1 is a side view of wire showingin dotted lines how one end portion is swaged or rolled in the firststep of the method to depress or ofiset and flatten it at one side; Fig.2 is a side view showing in full lines how the wires should be swaged;Fig. 3 is a top view of the swaged or rolled wire; Fig. 4 is aperspective view of two wires joined at right angles at the end of thesecond step of the method; Fig. 5 is a side view of the swaged wireshown in Fig. 2, after the eye has been formed by the second step of themethod; Fig. 6 is a section on line 6-6, Fig. 4:, after the step ofsoldering the parts, and Fig. 7 is a perspective view of the completejoint.

Referring to the drawings, an end-portion c of a wire or rod (4 ofmalleable metal is subjected to the action of suitable tools, to reduceits thickness considerably, expand it in width and to depress or olfsetand flatten one side of it at b, and to produce a convexity f on theother surface. The result of this action is shown by dotted lines inFig. 1, and in full lines in Figs. 2 and 3. It will be seen that theflattened end-portion 0 is simultaneously therewith bent out of axialalinement with the wire a. Also, that the width of the intermediate partof the endportion is considerably greater than the diameter of the wire.It follows that the widths of the flat surface 5 and the convex surfacef are greater than the wire. At the same time, the terminals 0, c ofsaid endportion 0 are each formed with a taper. This deformation of theend-portion of the wire so that the convex surface 7 extends from edgeto edge of said end-portion is preferably performed by a swagingoperation in a suitable press, and is the result of the bi-lateralcold-flowing of the metal.

The formed wire a is then put into a suitable press, not shown, withanother wire d at right angles to it so that the end-portion 0 may beclosed over the wire cl to form an eye c, Figs. 4 and 5, and the twowires will lie in substantially the same plane. The end-portion 0 isthus wrapped around the wire 03, the flat side 5 being on the inside andthe round surface f outside. When the eye 6 has been formed it will beseen that the tapered lengths c, c of the body of the eye merge into thebody of the wire. The parts are then united in such a way, if the besteffect is desired, by solder 9, that a ball-like efi'ect is produced,which in finished or nickeled articles is quite like orindistinguishable from a ball.

A joint so produced is solid and substantial when made with proper dies.It is less expensive than the use of balls, looks better than eyelets,and is cheaper than drilling and inserting Wires.

l/Vhat I claim is The method of producing a oint eye on a Wire or rod,which consists in depressing or offsetting, and flattening a part of thewire or rod relatively to the longitudinal axis thereof so as to expandit in Width and form a convex surface of greater Width than the wire orred, having tapering'inn'er and outer ends, and then bending said partso as to provide a ball-shaped eye of greater diameter than the wire orrod, the tapering inner and outer ends being merged into the body of therod.
